The audiovisual materials described in this guide illustrate three major occupant protection concepts: (1) The Dynamics of the Crash; (2) The Effectiveness of Safety Belts or Child Car Safety Seats; and (3) Myths and Misconceptions Related to the Use of Occupant Protection Devices. Items for presentation should be selected according to the time available and the interests of the audience. However, whenever possible, select the films that contain aspects of all three major concepts. It is suggested that the slide packages be used in follow-up presentations, either on child safety seats or safety belts. Each film or slide guide is designed to assist in selecting the materials that are most appropriate for the audience or situation. In addition, suggested presentation questions and answers have been provided. This document describes all of the audiovisual materials selected by the National Highway Traffic Safety Administration (NHTSA) for inclusion in various educational program kits. Although a particular kit may contain a few of these materials, the others may be obtained directly from NHTSA or the original producers listed on the last page of this guide.
